Saliva is a clear fluid in our mouths, formed by salivary glands. Although saliva is 99% water, saliva also contains white blood cells, electrolytes, proteins, enzymes, mucous, antimicrobial substances, and epithelial cells. Mouths that are deficient in saliva leave teeth vulnerable to cavities and the mouth’s tissues unprotected from injuries. However, excessive saliva complicates chewing, swallowing, and eating. Keeping a healthy amount of saliva flowing in a patient’s mouth is vital for good oral care as it prevents oral health issues such as gum disease and oral infections.

Purposes of Saliva

Saliva keeps the mouth lubricated, which prevents the buildup of harmful bacteria and tartar. Saliva also helps digest the food that we chew and swallow due to the enzyme amylase, which breaks down starches while the patient chews. Saliva helps remove food particles from between the teeth. Saliva also helps prevent bad breath. Saliva can maintain a healthy pH balance by counteracting acidic foods and beverages. Saliva can be tested by medical professionals to detect a variety of oral and systemic diseases as well as to measure hormonal balance by detecting steroids and sex hormones. Finally, the chemicals in saliva can remineralize teeth weakened by acid or bacteria due to the calcium and phosphorous in saliva.

Consequences of Saliva Imbalances

When a patient’s mouth has a lack of saliva, the condition is known as dry mouth. Dry mouth causes the mouth to become a breeding ground for harmful bacteria, leading to problems such as bad breath, cavities, and tooth decay. Conversely, producing too much saliva is called hyper-salivation. Hyper-salivation can lead to problems with eating and talking.
